Guys! You should add @Published before "var" to accept any user's changes in the View

I'm amazed by your productivity and the level of quality you put into your tutorials. Thank you for this video!

I clicked this video thinking it was going to be a half-assed video spread out across 3-4 videos. But no! Wow this was really well though out. You built it step by step and provided actual real world example of use. And used native libraries all the way without being carried away with the options. A concise and informative video with an accurate end result in the time of the video length! ☺️ /subscribed

Hands down one of the most approachable learning videos for Swift UI. Great work! Keep them coming!!!

Another fantastic SwiftUI example app, great stuff! Especially liked the tip about disabling the button based on the isValid computed property, as well as the reqres site for testing URLSession and JSON decoding.

There is a little change tot bindableobject and @ObjectBinding. They can't be used any more. Instead of that this is the new one: BindableObject -->> ObservableObject And: @ObjectBinding -->> @ObservedObject And extra to the variables: var quantity = 3 { didSet { update() }} -->> @Published var quantity = 3 { didSet { update() }} @Published has to be added Hope you don't mind me posting here :)

I was hoping for an app to order avocado toast, I suppose cupcakes will do. P. S. Great video!

Paul, You're awesome man! Keep doing your great work, Thank you!

Great videos. It does make me appreciate the ease of React and JSX especially when it comes to styling.

You are the best. The tut is very clear and an pleasure to listen to. Thank you very much !!!!!!!!!

Doode! That was badass! SwiftUI preview choked on launch of Cupcake Corner, lol! That was a truckload of material! Good thing the sim was working!

Awesome! I’ll have to explore the options for validations like in Eureka Forms, but now with this ..... is far easier and even prettier

This was awesome! I also noticed after playing around a little that you can use switch and ternary operators in SwiftUI now. I don't think that worked in the first beta.

Great work mate, keep them coming. Good teaching style.

Great tutorial. Of all the tutorials available, yours are the most concise and clear. On the picker list, why is the .tag[$0} necessary and what does it provide?

Great video Paul please make a video that shows how to customize swiftui components more🙏🙏

All the topics in this project are 100% required in every iOS job interview requirement I have seen locally, and there is so little good, complete and comprehensive material on URLSession and Codable. It was a real plus to see this in SwiftUI! I hope to see much more material on these topics! I will pay $$$ for good material!

Another great tutorial Paul - nice work. A couple of questions: - could the cupcake type be an enum with associated Strings and still be Codable? - how would you make the keyboard focus switch to the next address field when pressing the Return key?

Thanks for this amazing tuto!

Very nice tutorial. I have saved it to a list of SwiftUI tutorials for when it is out of Beta. I only have one mac and it's for my job and I do not like to install Beta software on it.

Overall, I’d say this is one of the best tutorials out there. Rather than just messing around with stupid math problems or other pointless things to illustrate how coding works, you’re showing a real world example of an app and we can see what is happening in real time. This is exactly what I’m ALWAYS looking for, and you do a great job at explaining things clearly and simply. That being said, might I offer a little a little/feedback/suggestion from my personal point of view as a complete beginner? When learning something new, in the beginning stages, my brain craves a semi rigid foundation of concrete ideas. I need some kind of a blueprint/template to be able to memorize and make sense of how different parts of a system work together and interact with each other. That means that I generally don’t do well with an instructor who teaches in a conversational style where they pepper the instruction with the live streams of thought that veer from learning these rigid associations-initially at least. For example, people who teach coding often have this habit of showing how you do something, while also saying “But you could also do it this way” or “However, if you wanted this, then you’d have to do *blank* instead.” Stuff like that. Stuff like this only confuses me and makes me uncertain which piece of information is the most important to absorb in that moment. So my approach to teaching would be to start with the most used standard practices in MOST situations, and then once the students have a solid foundation, then you can start riffing and philosophizing and exploring the different ways one can do something. I don’t mean to sound condescending but I think because it’s such second nature to think this way, many coders forget what it’s like to not know these things or how to think in this way, and they don’t realize that they need to slow it down any further. I’m talking about teaching coding as if you’re teaching a toddler.

Amazing lesson Paul... Thank you very much

Fantastically helpful video as usual Paul, thank you. I was just wondering, around 9:30, when creating the stepper to hold the number of cupcakes, why the first "order.quantity" has the $ in front of it but the string interpolation doesn't?

Nice One!, Clean code, Good quality of videos, Good Content, I like it, Thanks a lot uploading the new things over here!.

Thanks for the Great tutorial. Can you please make a tutorial to demonstrate mapKit with swiftUI, which include pin map and annotation and tapping the pin will show the new view with details about the place.

Great video with new Form concept

Fantastic video! Loving the Form component. I spent many hours developing user friendly forms in the storyboard. Can't wait until this is ready for production. In case anyone has XCode barking at them on the URLSession.shared.dataTask I had to change the code to this: URLSession.shared.dataTask(with: request) { data, urlResponse, error in guard let data = data else {

@Paul have you made a follow-up to this video with more recent versions of Swift and SwiftUI?

Great tutorial! My form "Section" didn't seem to work. No visible changes (as seen in the video). Using beta 3 now.

awesome like always, would love the see an app with some nice slide menu animation in swiftui

Great tutorial!

Yay!!! Networking 🙌🏾

Thank you for this great tutorial, Paul! You can use struct and @State except of class and @BoundableObject to get rid of didSet's. But it's a great visualisation what's going on!

Can you please add the ability to Tab from one textfield to another textfield when filling out the form?

It would be nice to see some videos that combine core data with URLSession and SwiftUI

First SwiftUI app completed! thanks for the tutorial!

Could you please update this great example now that BindableObject is deprecated in SwiftUI ?

If I taps the text field at the bottom, would it scroll up automatically? If so the framework is well designed.

Great video. Thanks for it :-)

Man you are awesome

How would you use AV Foundation in Swift UI?

When do we use 'PassthroughSubject()' instead of '()' ?

In a production app, how is the keyboard handled? Does the form slide up when the keyboard is enabled and how is the dismissal triggered? Also can you specify a specific keyboard or does the form automatically recognize which one the text field needs? Thanks. Learning so much from these videos.

Awesome!

Would I be able to create an appointment scheduler using this outline?

Can you tell us where does the data go once sent by the user … how can we send the submitted form data to an email I’d .. or is this just a tutorial with no ending

Nice!!

we don't have autocomplete for the navigationBarTitle for example...

Wish I could give this video more than one like

Is there a simple way to save the order selections to a list of some sort, to be able to order repeat items

Where does the tag[$0] come from?

Form rendering is not working for me in the preview. Simulator is fine, but my Xcode preview does not change when I switch code from VStack to Form as in the tutorial. So the elements render, but looks like a regular list and not a form. Using Xcode 11 Beta 3. OK to launch the sim every time, but I thought the point of SwiftUI was to avoid needing to do that.

I'd like to know how to validate text in Form, i.e limit text up to 8 characters, don't allow any special characters, etc. Please include these validations in your upcoming tutorials. Thanks

i'm trying to do the same app but using swift 11.3 and i got error class Order: ObservableObject, Codable { type 'Order' does not conform to protocol 'Decodable' self.placeorder() Value of type 'ContentView' has no member 'placeorder' var request = URLRequest(url: url)

Hi Paul, It is a great video and great app, simple and easy to understand. Please Paul, Can do it by Sending email for confirmation. instead of send by post. Can you please help How to send by Email. Look forward to your help in coding SwiftUI. Toan

Why do the confirmationMessage need to be a State?

or could you please give me update code for xcode 11.3 or 11.4

HELP: Im able to code forms and so on, but im struggling with getting the same visual result. On Small devices like the iPod touch it looks very similar. On Other devices (iPhone 8 - 12) the form has horizontal spacing and rounded corners - how do I get rid of that? I can't find a solution ...

Hi Paul, thank you for the fantastic video! I'm having troubles understanding under what circumstances we should use $ sign before the bindable object instance? For example, why should we use $ in the toggle initialization but not in the if condition? if order.specialRequestEnabled { Toggle(isOn: $order.extraFrosting) {} } Thanks again!

great

Awesome as always! 👌 7:30 How come code builds and runs with 0 ..< [O]rder.types.count (Type) instead of [o]rder.types.count (Instance)?!! What am I missing?

Please, is there github repo one could visit to see the complete code? Thank you!

For anyone else struggling to get Order to conform to Codable, check for typos in the CodingKeys cases. It's a shame these don't autocomplete.

static let types? there should be enum :)

BindableObject was replaced by : ObservableObject, @ObservedObject, and @Published. It technically works the same, so use that in your exercises. For basic usage refer to developer.apple.com/documentation/combine/observableobject

Code please! I want to make a sub app.

for anyone having issues with codeable and @published use these extensions, its a bit hacky but until this is support its the only way I could get it to build import Foundation import SwiftUI extension Published:Encodable where Value:Decodable { public func encode(to encoder: Encoder) throws { let mirror = Mirror(reflecting: self) if let valueChild = mirror.children.first(where: { (child) -> Bool in child.label == "value" }) { if let value = valueChild.value as? Encodable { do { try value.encode(to: encoder) return } catch let error { assertionFailure("Failed encoding: \(self) - \(error)") } } else { assertionFailure("Decodable Value not decodable. Odd \(self)") } } else { assertionFailure("Mirror Mirror on the wall - why no value y'all : \(self)") } } } extension Published:Decodable where Value:Decodable { public init(from decoder: Decoder) throws { self = Published(initialValue:try Value(from:decoder)) } }

Geez! Amazing how one misspelt word can bring SwiftUI to it's knees! "addSrpinkles" = "Cannot convert value of type" on this line: .navigationBarTitle(Text("Cupcake Corner")) in Xcode 11 Beta 2, in Beta1 it gave a different error on "Form", this after spelling it correctly in CodingKeys ))

Paul, any idea why I can't use the Form view in Xcode11-beta running on 10.15-beta. Xcode reports it as an unknown type.

It seems like we’re heading to a future where all apps kinda look the same as Swift UI doesn’t seem to leave much room for ‘design’. Not sure how I feel about that.

Very nice!! if it were possible, I would give 10 likes!! Thanks

Paul! Please hepl me! I don't use method Form. Xcode error: Use of unresolved identifier 'Form'

Xcode 11.0 beta (11M336w): Anyone else getting a 'use of unresolved identifier 'Form' error?

How do you disable mini map?

I give up. I can't get it to build.

Downloaded Xcode 11 beta 2 and Catalyna beta 2. It’s unusable. I can’t even open a Finder. Xcode doesn’t have iOS 13 sumulator and I can’t download it manually from Xcode preferences. Completly disaster.

It's curious, "Form" doesn't work for me....

you'r superb..i like your video.. Form is not working for me..plz suggesst

Not sure if I like this. Button looks like a TextField with placeholder text.

Most of this stuff is deprecated in swiftUI (expired code). I wasted half a day trying to figure it out. Paul Hudson please try and perhaps update your description so that people dont end up wasting their time. I wont subscribe for this reason.

bindable object is outdated u should say that somewhere man. ur the face of swift. smh.

I think you should warn people that this is a demo app. Putting your UI, data model, and networking code all in the same place is really bad practice. You're replacing the massive view controller problem with a massive SwiftUI problem.
